I found a babysitter that I liked through a Facebook group. I haven't met her yet, but we chatted through messages, and I think she seems like a good fit. She suggested coming to my house this week to meet my two boys and make sure I want to hire her in the future. My oldest son just started preschool, and that means he is coming in contact with germs from the other kids. He already has his first cold of the school year and has a slight cough and a runny nose. I let the babysitter know he has a cold, and she replied that she wants to reschedule for later in the week and for me to let her know how he's feeling. I get the impression that she doesn't want to be around my kids unless they are 100% well. Is this normal? I feel like little kids get coughs and runny noses frequently, and I'm not sure what I would do if I was depending on her and she cancelled at the last minute.
